murmur arr, or nnrsmme. rnmasrnv l in wheel tires, more especially of the pneumatic type.

The'lnvention has for its object the pro-.

visionof means whereby tires with worn treads can be repaired by applying new treads thereto, and particularly treads of other covers discarded owing to their having become rim out.

Another object is to devise means for securing the treads in place which will be absolutely secure, which will not 'be afiected by the action of the "heat generated from the travel or traction of the wheel over thesurface and which will not rub or mar the inner tube.

Other objects of the invention will be made apparent as the nature thereof is more fully seen from the following disclosure.

The invention therefore consists of certain instruments and features of construction substantiall as hereinafter set forth and defined by t e appendedclaims.

' In the accompanying drawings is illustrated thepreferred embodiment of 'my invention wherein'it will be understood that various changes and modificationsmay be made as 'relates. to details of construction and arrangement of parts without departing from the scope of the claims, and in' A a contact with said'tube and accordingly ob- Eigure. 1 is a transverse section of 'a-porwhich drawings:

tion of -a pneumatic wheel-tire embodying my invention;

. Fig. 2 is a fragmental portion of such a tire upon an enlarged scale, partly in side elevation and partly in section.

In carrying out my. invention, tire of preferably discarded or waste plece's of tire members '1 and2; the third piece 3 being interpos ed between these latter, said pieces or members. all being fixedly as-j sembled and preferably vulcanized together with or.without-stitching'jor riveting along the edges'jthereof, this arrangement thus providing for utilizing as indicated; otherwise'useless' parts of worn-out tire' members,

cost, are apparent. These severalparts 1, 2

and 3 are preferably conformed to the out line disclosed by Fig. 1, imparting thereto a tbickenedcentral or tread portlon, with inner tapering convergent end portions, thus reinforcing the tire where the greatest wear. is brought thereon, and providing for of the tread member and adjacent the corresponding or beaded edges of .said tire member. This means consists in providing for setting into the inner surface of the tire member in an annular groove or socket 5 therein, a piece of rubber or textile mate rial, as canvas, *6, and stitching or riveting the same to the tire member and the outermost or tread member 2 as at 6". The stitches or rivets are passed or directed through an inturned or folded under end.

portion or flap 7 of the rubber or textile piece 6, the other end portion or flap 8 of the latter being similarly folded within the socket, the body portion of said canvas or rubber piece thus being presented inwardl next to the inflatable tube '(not shown? whereby the rivets or stitches of the connection will be isolated or partitioned od from viate the danger of rubbing a hole t rough cheapening or lessening expense or purchase I the inner tube (not shown) due to friction.

It is understood of course that the stitching or riveting, as at 6, is performed before the body portion of the annular member 6 is inserted, withits end portion or flap 8'1nto the socket 5- of the tire member 1, the stitching or riveting operation being first edected through the end portion or flap 7, initially inserted into the socket, the other flap 8 then'being foldedl inwardly upon-the body atter, isposed thereon, pressed into the socket, the whole thus be by embedded in the tire as 'a-protector or guard a the transmission of coiunon, as above stated.

with the flap thus a heat to the thraded orstitched The tire thusproduced is, by reason of 1. A, wheel-tire, the inner member of which is provided with an annular member set mto the inner wall thereof, for receiving the fastening or connectin means between sald inner member an the outer member of the tire, adapted to guard or protect said fastening means from the heatmg action generated by the traction between the tire tread and the road or surface.

2. A wheel-tire, the inner member of which is provided with an annular member set into a socket in the inner wall of said inner member, said annular member receiving the fastening or connecting means between said inner member and the outer member of the tire and including a body portion with inwardly foldable' end portions serving as flaps, one of said flaps pro-,

neeepas riding for the passage of the fastening means therethrou h and the other flap adapted to inwardly fold upon the body ortion and the latter with the inwardly olded flap, adapted to be received within said socket and serve to guard or isolate said fastening means received by the aforesaid end flap.

3. A neumatic wheel-tire provided with an annu ar member set into the inner wall of one member therefor for receiving the fastening threads between said member and 1 the outer member of thetire, said annular member being adapted to prevent said fastening threads from rubbing the pneumatic tube and thus wearing punctures therethrough.

In testimony whereof I afiix my signature in presence of two witnesses.
